Do not forget to put your own connection string (inside " "). After this command gets executed successfully you can observe a Models folder has been created inside ServerSideSPA.App project and it contains three class files myTestDBContext.cs,
Cities.cs, and Employee.cs. Hence, we have successfully scaffolded our Models using EF core database first approach.

I did get the Models folder and the 3 class files, but I don't think I actually have a connection to the db, so I am wondering about "your connection string here"

Then I found the learnentityframeworkcore.com walkthrough for an existing database
here

If you are working with Visual Studio, you can use thePackage Manager Console commandsto generate the the code files for
the model. The equivalent command to the last CLI command just above is:

Re: Blazor - Scaffold-DBContext issues?

You need to specify a connection string for the tooling to use so that it can examine the database schema and generate the appropriate model files. So I don;t know how your first attempt worked unless you supplied a connection string.

The connection string is a standard database connection string. What you posted looks valid.

All the code is there to show the Employee records. Nothing came up

Probably my bad, but I'm struggling to follow. Where is all the code to show the Employee record? Where do you expect the data to "come up"? I'm unclear where in the process you expected data to appear and why you expect it.
